Transcatheter Mitral Valve Replacement: Structural and Hemodynamic Analysis
<p>Transcatheter mitral valve replacement (TMVR) is being developed to become a substitute therapy for surgery in prohibitive or high surgical risk patients to treat severe mitral regurgitation. A limited number of TMVR systems are under clinical evaluation. However, transcatheter mitral valve …

Multimodal treatment of women with mitral valve prolapse syndrome
Mitral valve prolapse is the most commonly occurring cardiac condition. It is a benign condition which affects as many as 10% of the population. Some patients have symptomatic mitral valve prolapse. This condition is referred to as mitral valve prolapse syndrome. Symptoms include: chest pain, …

Optimisation of Surgical Timing in Rheumatic Mitral Valve Disease
… which are generally older and with mainly single valve disease. Given the unique pathophysiology and demographics of rheumatic valvular disease, this may prove problematic. Rheumatic heart disease is epitomised by progressive mixed and multivalvular disease in children and young adults. Early …

Automated auscultation : using acoustic features to diagnose mitral valve prolapse
… to assess the condition of the heart muscle and valves. This process, termed cardiac auscultation, is the primary means of diagnosing cardiac disorders, the most common of which is Mitral Valve Prolapse (MVP). Yet, the practice of auscultation is highly fallible with reports of more than 80% of …

Advanced Echocardiographic Imaging In Dogs With Myxomatous Mitral Valve Disease
Myxomatous mitral valve degeneration (MMVD) is the most common canine cardiac disease. In the studies presented in this dissertation, we used advanced echocardiographic techniques to elucidate several aspects of MMVD in dogs. Our hypothesis was that the mitral valve (MV) morphology could have a …

Dynamic simulation of heart mitral valve with transversely isotropic material model
… element setting, the material behavior of heart mitral valve leaflet tissue. First, a mixed pressure-displacement formulation is used to implement the constitutive material behavior with general 3D elements. Second, a shell is formulated that incorporates the 3D material behavior by use of a …

Surgery for Degenerative Mitral Valve Disease:Earlier Intervention, New Procedures, and Better Outcomes
… of surgical techniques for degenerative mitral valve (MV) disease, and effects of these changes on surgical morbidity and mortality and hospital stay.Methods: From 1985 to 2010, 7,982 patients underwent surgery for degenerative mitral regurgitation; 5,045 had isolated MV procedures, …

Accuracy of Noninvasively Determined Pulmonary Artery Pressure in Dogs With Myxomatous Mitral Valve Disease
Development of pulmonary hypertension is an independent predictor of poor outcome in dogs affected by myxomatous valvular degeneration (MMVD). Systolic pulmonary arterial pressure is routinely estimated by Doppler echocardiography applying the simplified Bernoulli equation to the velocity of …

The longitudinal outcome of canine myxomatous mitral valve disease in dogs: The LOOK Mitral study
Myxomatous mitral valve disease (MMVD) is the most common heart disease in dogs. However, prospectively acquired data describing the natural history and prognostic factors in a large population of dogs affected by this disease are sparse. Thus, the Longitudinal Outcome of canine (K9) myxomatous …

MULTIPARAMETRIC SCORE FOR PREDICTION OF MYOCARDIAL FIBROSIS IN PATIENTS WITH MITRAL VALVE PROLAPSE: THE SCIMITAR TRIAL
… di pazienti con prolasso della valvola mitrale (PVM) — in particolare quelli affetti da malattia di Barlow — può sviluppare aritmie ventricolari (AV) e morte cardiaca improvvisa. Diverse caratteristiche cliniche e di imaging sono state proposte come potenziali fattori di rischio …

The effects of mitral annular dynamics, and the laceration of the anterior leaflet with transcatheter mitral valve replacements
High-risk patients in need of a mitral valve replacement created a demand for percutaneous MV interventions. With no dedicated devices currently on the market, clinicians have resorted to placing transcatheter aortic valves (TAV) into mitral annular calcification (Valve-in-MAC), failing mitral …

DIAGNOSTIC APPROACH TO MYXOMATOUS MITRAL VALVE DISEASE IN CAVALIER KING CHARLES SPANIELS: IDENTIFICATION OF EARLY DIAGNOSTIC FACTORS (MORPHOMETRIC PARAMETERS AND MIRNAS EXPRESSION)
Myxomatous mitral valve disease (MMVD) is the most prevalent acquired cardiac disorder in dogs and a significant contributor to both morbidity and mortality, especially among small breeds. Notably, the Cavalier King Charles Spaniel (CKCS) demonstrates an early onset and more rapid progression of …

Retrospective review of paediatric rheumatic mitral valve repairs and replacements done at Red Cross War Memorial Children's Hospital (RCWMCH) over a decade
… to review the surgical management of rheumatic mitral valve disease at our institution. Methods: We retrospectively reviewed 76 consecutive patients who underwent mitral valve surgery for rheumatic heart disease between 1998 and 2010. The results and follow-up were reviewed, where death and …

Evaluation of right ventricular function using conventional and real-time 3-dimensional echocardiography in normal dogs and dogs with myxomatous mitral valve disease
… in dogs with various stages of myxomatous mitral valve disease (MMVD), classified per the guidelines of the American College of Veterinary Internal Medicine, to those from healthy dogs. Animals: Twenty-two healthy dogs and 56 dogs with MMVD Methods: All dogs underwent conventional and 3D …
